To a/ZZ whom it may cmwerm.

Be it known that .1, EwALD GOLTSTEIN, a subject of the Emperor ofGermanyand a resident of Cologne, Germany, have invented certain new andv useful Improvements in Bottle-Caps, 4of which the following is aspecification.

Hy invention relates to bottle caps such as rial, and has for its objectto so construct the cap that it will be readily ontlopen l and also insuch-amanner as to save certain valuable parts of the cap and reventtheir separation from the bottle or ot er receptacle to which the cap isapplied. u Reference is to be had to the accompanying drawings in whichFigure 1l shows the neck of a bottle with one forni of, my improved capa plied thereto; Fig. Z is a cross section of anot er form of the capshowing its appearance before it is apsec'tional view of the neck of abottle with still another form of my cap applied thereto; and Fig. 5showsthe capof'Fig. 3 applied to a bottle. l I

.As illustrated in Fi suitable material suc 1. the cap consists of asaluminium, and

comprises an annular portion A which is' adapted to surround the bottleneck, and a removable central portionA A in the nature ofa disk which isso` connected with the annular ortion as tb facilitate separationtherefrom. For this purpose'l provide at the upper edge of the annularportion an inwardly bent portion A7 resting on the end surface of theneck and the outer edge of the central portion A is also 'bent inward,thus forming a contraction or groove A2 which facilitates the use of acutting tool, such as a knife. The groove also guidessuch knife as it ispassed aroundthe cap since the edge of the central portion A- overhangsthe inner edge of the portionTAT. Before the cap is applied, itsring-shaped portion A is straight,

after this portion has been slipped over the neck C of the bottle, whichis provided with a rubber washer B located in a groove C, the annularportion A is nicked or pressed -inward at such groove, so as to force itinto ln'this manner the cap is firmly connected With'the bottle. uWhenit is desired to'open the bottle,

`the central ortion Al is removed by cutting it away Wit a knife orother tool.

Among the advantages of my invention I desire to point out particularlythe great ease of opening the bottle, as the removal of the centralportion of the cap isy facilitated. Another advantage consists in thefact that the annular or surrounding portion A remains connected withthe bottle and there` fore permanently protects the. washer B againstinjury bydirt, dust or light. The bottles which are returned to thebrewery or bottling establishment still have the ring A.

and the'washer B upon them, and I thus save the said ring which, whenmade of aluminium as I prefer todo, is relatively valuable. The used.ring A would be removed at the brewery or bottling establishment and acomplete new cap would be substituted, but the original washer may beused a number of times.

The cap shown in Fig. 2 differs from the one iirst described chiefly'byhaving the diameter of the removable portion or disk a equal to that ofthe annular portion a, or contraction a is similar to the voneshowni'nFigl.

- In Fig. 3 I have stiffened kthe removable portion of the cap by meansof a separate disk D' whichis held by the contraction A2, the form ofthe cap being othe1wise'-the same as that in Fig. 1. Fig. 5 shows this.type of cap applied to a bottle. This strengthening disk may.' be ofadvantage in some cases to prevent injury to the removable up er portionof the 'ca which may be terme a sealing disk or sea ing portion. Iclaim:v1. The combination with a receptacle, of a cap having an annularportion surrounding the neck of the receptacle, and inwardly bentportion located' above said annular portion and resting on the endsurface 'of the neck, and a sealing portion extending across thereceptaclesmouth, and located above said inwardly bent portion andprojecting out- 8o i The throat ICO wardlyso aste overhang the same andform IOS IIC
